Verdict
The clearest difference is rating: Perse Visualizer at 5.0 against BioViewer's 1.0. Perse Visualizer also leads on review sentiment (50% vs 33%) and ratings volume (7 vs 1). BioViewer's advantage is ads (none vs shown) and update cadence (every 9 days vs every 2 months). On price, in-app purchases and device support there is nothing between them.
